It would require using a poly blend but there are fabric crayons that the kids could use to draw on paper and then you iron it to transfer it to fabric - I have a set of these crayons and it is really easy. I have all kinds of project ideas for my kids. If they wrote words, it would transfer backwards, of course. The finished project is washable in cold water but cannot be put in the dryer. The crayons are available at Hobby Lobby and possibly your LQS (that's where I found mine).
